Article Preview

The creep properties of type 316LN SS welded by the SAW process have been evaluated. The creep tests for both the base and weld metals were conducted with different stress levels at 550oC and 600oC. The creep-rupture time of the weld metal did not show a large difference when compared to that of the base one, though it exhibited a little lower value at 600oC. The creep rate of the weld metal was lower than that of the base one at the same stress and rupture-time conditions. Especially, the creep-rupture ductility of the weld metal is found to be decreased by about 60%, compared to the base one. This is due to the decreasing of tensile elongation and the increasing of the yield stress in the weld metals.
